In union operation x->y and x->z But according to fd rules x cannot Have different values.can you please tell me why.

[@rm764]

Have u found the answer.. If yes then tell me..I hv Same confusion

[@preetmehta1008]

Fd rules basically says that if x->y holds true...then with help of x, unique y can be found..hence x->z means that with help of x, unique z can be found...therefore, x->yz basically means that with x, unique values of y and z can be found... there's no violation in fd rules

[@Healthylifestyle924]

In transitive rule a to b and b to c then a to bc is hold not a to c sir because we get two different values on the same value of a?

[@parvadave1379]

Ty☺

[@RoshanKumar-xu3nw]

Union --If x->y && x->z then x->yz How here in case of union x has two value before u said f(x) =y , x can't have two different value ?

[@bikramchatterjee8296]

Sir is functional dependency from "A" to "B", implies that we can find every value of B from A, and is it mandatory that every value of A cantains a corresponding value or result in B? please help me sir.
